Typ Nürburg 460 engine (1929–1932) For 1929, the company's first eight-cylinder model was extensively reworked by the newly appointed Technical Director Hans Nibel. The 8-cylinder engine and most other technical details were carried over unchanged from the 1928 car including the ratios chosen for the four-speed manual transmission.
Typ Nürburg 500 engine (1931–1933) In 1931, the car became available with an enlarged 4,918cc engine which now also featured a twin downdraft carburettor. Maximum output was now listed as at 3,100 rpm and claimed top speed increased to 110 km/h (69 mph).Oswald, p 233

The 4,918cc side-valve engine with its twin downdraft carburetor was unchanged, as were the four-speed optional overdrive transmission, wheelbase, and list of standard body types.Oswald, pp 260, 262 & 263
Typ 500 engine (1936–1939) 1936 saw an increase in claimed maximum output from the engine to at 3,300 rpm. The cylinder capacity at 4,918cc was unchanged, but there was a marginal raising of the compression ratio. The claimed top speed was now raised further to 123 km/h (76 mph).Oswald, p 263 The model was discontinued in 1939 without any immediate successor. Twenty-four years passed before the next 8-cylinder engined Mercedes-Benz appeared; with the Mercedes-Benz 600, in 1963.
